Wake-up
1. What is the purpose of stomata?
1. Explain the difference between
phototropism and gravitropism.
1. There are 4 different groups of plants:
Try to list them. Think about what you
see outside. (Think on this one!!!)
What is a Spore?
Reproductive
structure that
can grow into
a new plant
without
fertilization
What is a Seed?
Reproductive
structure that
results from
fertilization
What is Nonvascular?
Plant that does not
have vascular tissue:
•No xylem to
transport water
•No phloem to
transport
glucose (food)
What is Vascular?
Plants that do have vascular tissue:
•Xylem transports water
•Phloem transports glucose (food)
Nonvascular/Non-seed: Characteristics
Small in size
Nonvascular/Non-seed: Characteristics
Must grow very close to the ground
Nonvascular/Non-seed: Characteristics
Reproduce using spores with a sporophyte
Spores
Nonvascular/Non-seed: Characteristics
Does NOT have
vascular tissue
Water moves
through
osmosis
Glucose moves
through
diffusion
Nonvascular/Non-seed: Habitat
Must live near a water source; it is needed for
basic water needs and fertilization
EXAMPLE: Mosses
EXAMPLE: Liverworts
EXAMPLE: Hornworts
Vascular/Non-seed: Characteristics
Does not lay flat to the ground; grows taller
Vascular/Non-seed: Characteristics
Has vascular tissue; Xylem moves water;
Phloem moves glucose (food)
Vascular/Non-seed: Characteristics
Reproduce using spores with a sporophyte
Vascular/Non-seed: Habitat
Live in damp/humid environments; need water
for fertilization
EXAMPLE: Club Ferns
EXAMPLE: Horsetails
EXAMPLE: Ferns
Vascular/Seed in Cone: Characteristics
Have needles which is a modified leaf
Vascular/Seed in Cone: Characteristics
Have cones; Cones are the female
reproductive structure
Vascular/Seed in Cone: Characteristics
Gymnosperm - Naked
seeds; seeds are in a
cone instead of
covered in a fruit
Vascular/Seed in Cone: Characteristics
Xylem
moves
water
Phloem
moves
glucose
(food)
Vascular/Seed: Habitat
Does NOT
have to live
near water;
sperm can be
airborne
Vascular/Seed: Habitat
Conifers can live EVERYWHERE; even
extremely cold climates
Vascular/Seed in Fruit: Characteristics
Have Flowers
Vascular/Seed: Characteristics
Angiosperm - Covered seeds; seeds
are enclosed in a ovary
Vascular/Seed in Fruit: Characteristics
Has seeds; Contain embryo, endosperm (food
source), and protective coat
Vascular/Seed in Fruit: Characteristics
Xylem
moves
water
Phloem
moves
glucose
(food)
Vascular/Seed in Fruit: Habitat
Angiosperms can live EVERYWHERE; most
diverse group of plants
Pistil:
Female
Ovary: Eggs
Petals:
Stamen:
Attract Pollinators Male
Locule:
Chamber of Eggs
Sepals:
First leaves
on bud Holds Ovary
Receptacle:
Stigma: Sticky to
attract pollen
Pistil:
Female
Style: “Neck” of the
Pistil
Ovary
Eggs: Sticky to
attract pollen
Anther:
Contains Pollen
(Sperm)
Stamen:
Male
Filament:
Anther Stalk
